Twisting exerciser

ABSTRACT

A twisting exerciser includes a base with a tubular extension and multiple first adjusting holes defined through a periphery of the tubular extension. A cushion has a cylindrical bottom received in the tubular extension and provided with multiple second adjusting holes defined to correspond to the first adjusting holes and multiple legs extending out therefrom. A pin extends into one of the first adjusting holes and one of the second adjusting holes to secure engagement and a relative position between the tubular extension and the cylindrical bottom. A stepping board is securely mounted on and supported by the cushion. The stepping board is able to be twisted and rocked so as to provide an exercising effect to a user.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an twisting exerciser, and more particularly to an twisting exerciser which is simple in structure and able to provide various operation statuses.

[0003] 2. Description of Related Art

[0004] A conventional exerciser is shown in FIGS. 8, 9 and 10. The conventional exerciser includes a base (40), a supporting seat (50), a twisting seat (60) and a top cover (70).

[0005] The base (40) is placed on a plane to support the weight of the other components of the exerciser. The supporting seat (50) has multiple extensions (52) extending outward and spatially apart from each other. Multiple first adjusting blocks (54), second adjusting blocks (56) and third adjusting blocks (58) are concentrically and annularly formed on the supporting seat (50). Each of the first adjusting blocks (54) has a maximum height. Each of the third adjusting blocks (58) has a minimum height and each of the second adjusting blocks (56) has a medium height when compared with the first and the third adjusting blocks (54,58).

[0006] The twisting seat (60) is mounted on top of the supporting seat (50) and has multiple receiving holes (621) each defined in a corresponding one of supporting blocks (62) formed on a bottom face of the twisting seat (60). The top cover (70) is mounted on top of the twisting seat (60) to function as a stepping pad for the users. After the first adjusting blocks (54), the second adjusting blocks (56) or the third adjusting blocks (58) are received in the receiving holes (621) of the supporting blocks (62) and the top cover (70) is placed on top of the twisting seat (60), the user is able to stand on the top cover (70) and exercise.

[0007] Because the first, second and third adjusting blocks (54,56,58) are made of rubber, when the first adjusting blocks (54) are received in the receiving holes (621) of the supporting blocks (62) the user needs minimum effort to twist the twisting seat (60). When the third adjusting blocks (58) are received in the receiving holes (621) of the supporting blocks (62) the user needs maximum effort to twist the twisting seat (60). When the second adjusting blocks (56) are received in the receiving holes (621) of the supporting blocks (62) the user needs medium effort to twist the twisting seat (60).

[0008] Although the conventional exerciser does provide the user an exercising function, the conventional exerciser suffers from the following drawbacks:

[0009] High Cost

[0010] Because the conventional exerciser contains up to four elements and for each of the four a separate mold is required, the cost for making the elements is high.

[0011] Dull

[0012] The conventional exerciser can only provide a single exercising method, which is below the expectation of the user. Normally when purchasing an exerciser, the user expects the exerciser to provide various exercising functions so that the user may choose from different options instead of being stuck with a single exercising method. The conventional exerciser in FIGS. 8, 9 and 10 is the type of exerciser that provides only one exercising method.

[0013] To overcome the shortcomings, the present invention tends to provide an improved exerciser to mitigate and obviate the aforementioned problems.

SUMMARY OF THE INVENTION

[0014] The primary objective of the present invention is to provide an improved twisting exerciser which is simple in structure and provides different exercising methods.

[0015] Another objective of the present invention is to provide an improved twisting exerciser which is able to provide the user with a torso twisting effect and an aim exercising effect.

[0016] Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027] With reference to FIGS. 1 and 2, the twisting exerciser in accordance with the present invention has a base (10), a cushion (20) and a stepping board (30).

[0028] The base (10) is placed on a plane and includes a tubular extension (12) formed on a center of the base (10) and provided with multiple first adjusting holes (14) defined through a periphery of the tubular extension (12) to receive therein a pin (16).

[0029] The cushion (20) has a cylindrical bottom (22) with multiple second adjusting holes (24) defined in an outer face of the cylindrical bottom (22) to correspond to the first adjusting holes (14) and multiple legs (26) extending outward from a top face of the cylindrical bottom (22) of the cushion (20). Multiple securing holes (261) are defined in a top face of the cushion (20). A recessed area (262) is defined in a center of the top face of the cushion (20).

[0030] The stepping board (30) has a protrusion (301) (shown in FIG. 3) formed on a bottom face of the stepping board (30) to correspond to the recessed area (262), multiple cutouts (32) defined in a peripheral edge of the stepping board (30), multiple securing rods (34) each mounted in a corresponding one of the cutouts (32) and multiple pairs of oppositely formed handles (36) formed on the peripheral edge of the stepping board (30).

[0031] With reference to FIG. 3, when the twisting exerciser is in assembly, the cylindrical bottom (22) is received in the tubular extension (12) and the first adjusting holes (14) corresponds to the second adjusting holes (24). A first screw (11) is used to extend through a bottom of the base (10) and into a bottom of the cylindrical bottom (22) to secure engagement between the base (10) and the cushion (20). The protrusion (301) is inserted into the recessed area (262) and then four second screws (31) are used to extend through the stepping board (30) and into the securing holes (261) on the top face of the cushion (20) to secure engagement between the cushion (20) and the stepping board (30).

[0032] It is noted from the drawing of FIG. 3 that the cylindrical bottom (22) has a height larger than that of the tubular extension (12) such that after the cylindrical bottom (22) is received in the tubular extension (12), a portion of the cylindrical bottom (22) extends out of the tubular extension (12). After the finding that a portion of the cylindrical bottom (22) extends out of the tubular extension (12), the top face of the cushion (20) including the legs (26) extends outside the tubular extension (12).

[0033] Therefore, with reference to FIG. 4, after the foregoing assembly, the user is able to stand atop the stepping board (30). Because the cushion (20) is made of rubber, the user standing on top of the stepping board (30) is able to rock. FIG. 5 shows that the user is able to use the elasticity of the cushion (20) to swing. However, when the user feels that the effort required to rock or twist the stepping board (30) is too large, the user may readjust a relative position between the tubular extension (12) and the cylindrical bottom (22) by realigning one of the first adjusting holes (14) with a different one of the second adjusting holes (24) so that the effort required to rock or twist the stepping board (30) is changed.

[0034] With reference to FIGS. 6 and 7, it is noted that the pair of ropes (40) may be provided to the twisting exerciser of the present invention. Each of the ropes (40) is provided with an elastic element (42) with two distal ends. One distal end of the elastic element (42) is provided with a hook (44) and the other distal end of the elastic element (42) is provided with a holder (46). The hook (44) is detachably hooked to one of the securing rods (34). Preferably, the two hooks (44) are hooked to two opposite securing rods (34) so that the user not only is able to stand on the stepping board (30) to twist or rock, but also is able to have an arm exercise.

[0035] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
